AI Coach Learns to Give Fitness and Sleep Advice (But Still Needs More Training)

This research introduces an LLM fine-tuned to act as a personal health coach, offering personalized insights and recommendations for sleep and fitness based on wearable data and case studies. While the model performs well compared to human experts, particularly in sleep medicine, limitations exist due to potential sample biases and the possibility of the AI generating inaccurate information.

Possible Conflicts of Interest

This study was funded by Google LLC. All authors are employees of Alphabet and may own stock.

Identified Weaknesses

Unrepresentative sample

The case studies and the Fitbit research dataset may not fully represent the diversity of the general population, potentially limiting how broadly applicable the findings are.

Synthetic feedback limitations

The reliance on synthetic user feedback in the fitness case studies might not accurately reflect real user experiences and preferences.

Potential for confabulations

Despite demonstrating strong performance, there's still a risk of the model making stuff up, which could hinder its reliability and safety in real-world applications.

Rating Explanation

The research demonstrates a novel approach to personalized health monitoring using LLMs and wearable data. While promising, limitations regarding sample representation and potential for confabulation prevent a top rating.
